Abstract
Spectrum use will undoubtedly move to the terahertz (THz) frequencies in the beyond fifth-generation (B5G) mobile system era. With enormous bandwidths far greater than the amount available in the microwave and millimeter-wave
(mmWave) bands combined, THz communications will open up new frontiers for exciting services and applications requiring ultra-broadband connectivity. In this work, we evaluate the performance of a candidate B5G scenario with THz-enabled massive MIMO access points (APs) mounted on street lampposts
to serve pedestrian users. Using spectral efficiency (SE) and energy efficiency (EE) as metrics, the performance of hybrid precoding (HPC), analog beamforming (ABF) and singular value decomposition (SVD) precoding are compared. We also show the impact of carrier frequency, bandwidth, antenna geometry and antenna gain on the network performance. Our results reveal the optimal EE and SE points which are critical design factors for the green and sustainable operation of next-generation mobile networks.
